Age, condition, and replacement costs in deposit disputes
Older property is not automatically worthless, and a new replacement bill is not automatically the tenant's responsibility. Review the governing rule and the evidence behind the claimed loss.

How sources are checked →The crucial distinction: tax accounting is not tenant liability
IRS Publication 527 explains rental income, expenses, and depreciation for federal tax reporting. It does not purport to decide a security-deposit dispute. A tax recovery period should not be copied into a formula that labels a landlord's charge valid, invalid, or collectible.
There is no universal formula such as “replacement cost × remaining tax life.”
A court may consider age or value evidence, but the relevant measure and burden depend on the jurisdiction, claim, lease, proof, and facts.
What to review instead
Condition
What did the move-in record show, and what changed by move-out?
Cause
Is the condition tied to tenant-caused damage, ordinary deterioration, maintenance, or another cause?
Scope
Could cleaning or localized repair restore the condition instead of broader replacement?
Cost
What actual invoice, receipt, estimate, labor record, or work order supports the amount?
Age
When was the item installed or purchased, and what maintenance or prior repairs occurred?
Betterment
Did replacement restore the prior condition or materially improve the property?
Example: an old-carpet replacement claim
Suppose the landlord lists $1,200 to replace carpet that was already several years old. The age is relevant, but age alone does not produce a legally correct dollar amount. Ask when and where the carpet was installed, its quality and prior condition, what damage is documented, whether cleaning or spot repair was feasible, which rooms were replaced, what was actually paid, and whether the work improved undamaged areas.
The defensible conclusion at this stage is that the charge needs factual support—not that a generic lifespan makes it automatically $0 or automatically valid.
State law controls the legal question
The rules are not identical. For example, Cal. Civ. Code § 1950.5 addresses permitted deposit claims, ordinary wear, accounting, and documentation. RCW 59.18.260-280 addresses itemization and supporting estimates, invoices, receipts, or repair documentation. Neither source turns an IRS table into a universal tenant-damages formula.
Start with the official source for the property state, then check local rules and the lease. A statute can also change, and an exception or disputed trigger can alter the result.
A practical evidence request
- Identify each charge, location, and claimed condition.
- Request move-in and move-out photos and inspection records.
- Request installation, purchase, maintenance, and prior-repair records where age matters.
- Request invoices, receipts, estimates, work orders, or a labor-and-material log.
- Ask why the chosen repair scope was necessary and whether a narrower repair was considered.
- Compare the response with the current state statute and any applicable local rule.
Frequently asked questions
Common questions about age, condition, repairability, and cost evidence.
Does IRS Publication 527 decide what a tenant owes for damage?
No. Publication 527 explains federal tax treatment for owners of rental property. Its recovery periods do not automatically establish tenant liability, an item's market value, or damages under state landlord-tenant law.
Can age still matter in a security deposit dispute?
Yes. Age, prior condition, remaining value, repairability, actual cost, and whether replacement improved the property can all be relevant. Their legal effect depends on the governing law, lease, evidence, and disputed facts.
Is there one legal useful life for carpet or paint?
No universal tenant-liability table applies everywhere. Ask for installation and maintenance records, compare move-in and move-out condition, and check the controlling state and local rules before relying on any lifespan estimate.
What should I request for a replacement charge?
Request the installation or purchase date, prior-condition records, photos of the claimed damage, repair-versus-replacement reasoning, the affected area, invoices or estimates, and the calculation used to assign the cost to you.
